This invention relates to a conveyor system :for handling objects such as packing cases, and relates more particularly to an improved conveyor system Iprovided with a movable, tiltable section whereby packing cases riding along the conveyor system may be tilted out of line to facilitate the loading thereof.

An object of this invention is toy provide a tilting section in a packing case conveyor system adapted to shift a packing case resting thereon out of the main conveyor line and simultaneously to tilt the case and to render the bottom-most section of the case on the tilted section of the conveyor system more easily accessible for proper packing thereof.

Another object of this invention is the provision of tilting means in a section of a conveyor system adapted to tilt an Object, such as a packing case, riding thereon to the desired angle and to lock said case in tilted position automatically in a single operation.

Other objects of this invention will appear from the following detailed description and the accompanying drawings.

In the drawings,

Fig. l is a side elevational view of the novel tilting section of my invention having a packing case thereon, showing mechanism for drawing '8 Claims. (C1. 22S-'129) the section out of line and simultaneously tilting it, and

Fig. 2 is a front elevational view of a conveyor line having the novel tilting section of my invention in combination therewith showing the handle whereby the tilting section and the case thereon may be drawn from the main conveyor line and placed in tilted position.

Like reference numerals indicate like parts throughout both `views of the drawings,

Referring now to the drawings, and more particularly to Fig. 2, the main packing case conveyor line employed in connection with my novel tilting section comprises, in its several parts, stationary sections 3, only portions of which are shown, together with a short stationary section 4 intermediate thereof in the gap formed by the removal of the tilting section. Thusthe novel tilting section of my invention, generally indicated by reference numeral 5, is so positioned that the framework thereof straddles stationary section 4. The construction and operation of said tilting conveyor section is hereinafter described. Stationary sections 3 and 4 are provided with a plurality of cylindrical rollers B, which rollers are rotatably mounted in horizontal supporting members 'I and 8, respectively. The several supporting members 'I are set on posts 8 anchored to the flooring by suitable means (not shown). Supporting member 8 of the central or stationary section 4 is set on posts I0 fixed to the flooring by bolts II. The stationary sections 3 and 4 of the conveyor system are capable of carrying any heavy object such as a packing case, for example, the latter being indicated by reference numeral I2. Packing case I2 may be moved along the conveyor line independent of tilting conveyor section 5, it being large enough to bridge the gap formed when the tilting section is removed from the conveyor system.

The tilting conveyor section 5 of my invention comprises a framework consisting, in its several parts, of a pair of horizontal rectangular structural members I3 having a plurality of cylindrical'rollers I4 rotatably mounted therein, and a U-shaped channel member I5 set beneath and attached to members I3 to provide additional rigidity and strength. vChannel member I5 is connected to rectangular members I3 through the brackets I6 mounted on channel I5 by means of bolts I1. Brackets It are nivo-tally linked to a second pair of brackets I8 through pins I9, brackets I8 being fixed to members I3 by means of bolts 20.

The entire tilting conveyor section 5 rides out of the main conveyor line consisting oi' stationary sections 3 and 4, on a plurality of casters 2l. Casters 2I are attached to the lower side of channel I5 in any suitable manner and are provided with grooved wheels 22 set on tracks 23 which are anchored to the flooring by bolts 24.

To effect the desired tilting action in conveyor section 5, when the latter is drawn out of the main conveyor line, there is provided an inclined stationary trackway which consists of a pair of guide rails 25 mounted on posts 26 and 2l. 'The latter are anchored to the flooring by bolts 2B and 29 which pass throughv angle irons 3|) and 3|, respectively. Posts 2@ and 27 are welded to said angle irons and the latter serve to give the posts greater strength and rigidity. Guide rails 25 which comprise the inclined trackway each contains a roller 32 rotatably mounted on a short shaft 33. Shafts 33 are attached to dependent legs 34 welded to angle irons 35 which, in turn, are welded to the lower side of rectangular members I3. l

In order to draw the conveyor section 5 outof the main conveyor line and to effect the tilting of packing case I2, when the latter is in posil tion on said tiltingconveyor section 5, as shown in Fig. 2, the operator grasps the handle 36 atcase I2 is in the position I2' shown in dot-dashv lines in Fig. 1 and comes to rest on a brake ory stop member 31 pivoted on post 31. Stop member 3'! and post 3l are not shown in Fig. 2 for the sake of clarity. The upper surface of stop member 3'! is covered with rubber to prevent packing case I2 from moving, laterally of the tilting section, on rollers I4. As the conveyor section is tilted as far as it will go, it is simultaneously locked into tilted position by the actionof atrigger. 38 which hooks under a catch 3 9." Inl position I2 the packing case may be packed efficiently since the bottom thereof vis ,within easy reach.

'j AAfter case.I2 has been packed and is to be returned to the main conveyor line, the operator forces lever 40 toward handle 36 which causes rod 4I to move upward. This action draws trigger 3B. from catch 39 since the upward movement of rod 4I causes trigger 38 to pivot in bracket 42 in.which said trigger 38 is mounted, and to be thus released. The downward pull exerted by the weight of loaded case I2 together with a slight Ipush ori-handle 36 by the operator after trigger 38 isreleased, rolls the tilting conveyor section 5 backinto the main conveyor line. When both thestationary and tilting conveyor sections are in normal running position, rollers I4 are lined upvwith rollers 5 ofthe main conveyor. While .rollers 1 I4 may be on the same level as rollers 6, as shown in Fig. 2, rollers I4 are preferably set .slightly higher than rollers 6 so that the loaded packing case I2 may again be started along vthe main'conveyor line with as little effort as possible.

;;. Itis to be understood that the foregoing detailed description is given merely by way of -illustration and that many variations may be made thereinwithout departing from the spirit of my invention.

. Having described my invention what I desire to-v secure by Letters Patent is:
